I have collected hundreds of gemstones over the past 40 years, including some high end rubies, sapphires, emeralds, tourmalines, demantoids, topaz, aquamarines, etc. Some have papers, most do not.
I would consider swapping these for some land, a house, or ?? up to $250K or so. Can use gemval.com valuations (wholesale) or your jeweler.
Send me pics and specs on what you have.
